Answer:
x = 4.5
Step-by-step explanation
When z is 6 that means x is 1.5 which means that when z is 18 then x is 4.5 because we add 3+1.5 which is 4.5
Answer:
See below.
Step-by-step explanation:
Are you sure it's 4 liters to 250 miles, and not 4 liters to 250 milliliters?
If it is 4 liters to 250 miles, then it equals
0.016 liter : 1 mile
If it is 4 liters to 250 ml, then it is
4 liters : 250 ml
4 liters : 0.25 liter
16 liters : 1 liter
16 : 1
Answer:
Its non linear because of the x squared. This would indicate an ever increasing answer, not one that has a constant rate. This equation would be quadratic.
378
Because a multiple of both 7 and 3 is 21, and 21*18=378.
(3x-2)(3x+ 2)
Multiply each term in one set of parentheses by the other terms:
3x x 3x =9x^2
3x x 2 = 6x
-2 x 3x = -6x
-2 x 2 = -4
Combine to get:
9x^2 + 6x - 6x -4
Combine like terms:
9x^2 - 4
The value of a would be 9.
